Nautilair variable speed brushless DC blowers have been engineered to deliver a measured air/fuel mixture in gas-fired burner systems for optimized combustion and reduced nitrous oxide and carbon monoxide emissions. These pre-mix blowers offer practical solutions for a wide range of applications, including commercial and residential boilers, food service equipment, kilns, and fuel cells, among others.
They serve as ideal alternatives to conventional speed or two-speed blowers, intake damper systems on fixed speed blowers, or inverter-driven variable speed blowers. When used with a modulating gas valve, these compact, lightweight, rugged, versatile, and high-speed blowers can suit a wide range of system designs.
Speed can be adjusted internally with an on board potentiometer or with an external PWM or DC control that actively varies blower performance (eliminating the need for complex air intake damper systems); internal electronics convert AC input to DC; and blowers typically operate in excess of 20,000 hours virtually maintenance-free.
Among options, an electronic control drive integrating a factory-programmed digital signal processor (DSP) and custom option cards can customize performance for specific application requirements.
